Cheap Tech Privacy Hacks for Mobile Devices

  1. Use Signal for encrypted text messaging. Hint: Both you and your text message recipient need to both install and use Signal for the encrypted messages to flow securely.
  2. Use ProtonMail or the K-9 Mail app on your device which is open source and supports use with OpenKeychainโ€™s Easy PGP app for encrypted emails.
  3. Use Telegram for private chat and video messaging. Telegram uses very strong End-to-End Encryption (E2EE) that consists of 2048-bit RSA encryption along with 256-bit symmetric Advanced Encryption Standard (AES) encryption. Telegramโ€™s encryption is so solid that several governments have outright banned this app because they couldnโ€™t backdoor the encryption to snoop on their citizens.
  4. Use the Hushed app to create burner phone numbers for instances in which you have to give your phone number out to marketers or send texts, multimedia to someone you donโ€™t necessarily trust. Hushed allows you to manage fake burner phone numbers in one app. Itโ€™s not my favorite price โ€” free, but itโ€™s not expensive either.
  5. Use the DuckDuckGo privacy-themed search engine app to search for stuff on the internet from your smartphone or other mobile devices. The DuckDuckGo browser doesnโ€™t log your browsing history or data like Google, Yahoo, or Bing do.

Trust No One. Verify Everything. Leave No Trace.
